Fig. 18 is the tone arm raising and lowering lever. y

Referring more particularly to the drawings, a supporting motor boardand associated cabinet is illustrated at 10 and more clearly seen inFig. 5. The usual horizontally rotatable turntable 11 is provided, androtated byv a central vertical shaft 12 which is preferably turned by a'suitable electrical motor' 14.-. The usual toneA arm 15 and soundbox 16are provided mountedv through the motor board 10, the tone arm 15 beingpivoted for vertical movement about a horizontal axis 17 5 and beingrotatable by rotation-of the tubular sound conducting sleeve; 18 towhich it is piv' o ted. A suitable escutcheon Aplate 19 may be providedfor Securing the sleeve 18 in proper relation with the motor board 10.

Mounted for actuation by movement of the tone arm 15, there is provideda control switch 20. The switch includes avertical loperating link 21terminating in a horizontal arm 22, the end of which is bifurcated toprovide upper and lower contact members 23 one end `27 of the uppercontact 25 is joined for electrical connection with the lower contactsurface 26 by a conducting bar 28, while the opposite end 29 of thesurface 25 is insulated from the end 27.

As illustrated in-Fig. 6, any suitable source vof electrical energy maybe supplied as at 30. With the arm 22 inthe position shown in Fig. 6,current is supplied from the -sourcel of potential 30 through conductor31 and the slip ring connection 32, through the vertical link 21, arm 22and the upper contact member 23 to the fend 27 of the upper contactsurface 25;'thence through the conducting member 28, conductor 33 tosupply energy for rotating a. suitable electrical motor l34. The circuitis completed from the motor 34 to the source of potential 30 through theconductor 35. As will be hereinafter described, the motor 34 is adaptedto control the movement of the tone arm lifter and rec.-v ord-reversingmechanism. After consideration of this mechanism it will be noted thatafter reversing the record and lowering of the y sound box 16 upon theouter periphery of the soundrecord, the contactl member 23 will engagethe end 29 of the upper contact surface 25; thus, breaking theelectrical circuit through the motor 34 and completing the electricalcircuit in the source of potential 30 through conductor 31, slip ring32, link 21, arm 22, end 29 andconductors 36 and 37 through theelectrical motor 14 which is adapted for connection with the shaft 12for rotating the turntable. A'

It may be readily seen that as the sound box 16 moves toward the centerof the record, and the end of the sound groove, it approaches ',the end27 of the upper surface 25, thus breaking the circuit tothe motor 14 andinitiating movement of the motorv 34, upon the energization of which thesound box is lifted as will hereinafter be described, causvand motorsherein described.

cuit to themotor 14 will be completed as hereinbefore described.

It will be understood that the specific form i of switch hereindisclosed and the circuit connections and power supply for operatingcludes the provision of mechanical equivalents in place of theelectrical switch circuit For operating the tone arm record reversingmechanism, it will be noted by referring to Figs. 3 and 7 that the motor34 is-provided with a shaft 40 upon which is mounted a worm gear 41adapted to engage the peripheral edge teeth 42 of a main driving gear43. By referring to Figs. 10 and 12v it will be noted that the gear 43is provided on either side with segmental bevelled gears 45 and 46. Eachof the bevelled gears 45 and 46 extend a distance of approximatelyone-sixth of the circumference of the wheel 43; their terminating endsbeing adjacent on opposite sides of the wheel. Mounted on either side ofthe main driving gear 43 and to mesh respectively with the bevelledgearsegments 45 and 46 there is provided Aa pair of cooperativelybevelled gears 48`and 49. They cooperating gears 48 and!k 49" arecarried upon inclined shafts 50 and 51. upon the opposite ends of whichare mounted gears 52 and 53 for rotation w1th the cooperating gears 48and 49 respectively. The gears 52and 53 are both in mesh with a gear 54carrie-d upon the extremity and adapted to rotate a shaft 55 similarlyinclined to the shafts 5() and 51. Theshafts 50, 51 and 55 are suitablymounted for rotation 1n brackets 56 which may be suspended from themotor board 10 in any desired manner.

lt will be understood that the neutral posi- 'no whereby the shaft 5 5will 'be rotated in the direction of the arrow A, and thus rotate theflange 58 in the direction of its arrow A, as shown in Fig. 10.

When the end of the segment 45 has reached the gear 48, it will be seenthat the wheel 43 lifting and is free to move through approximatelytwothirds of a" revolution, at which time the bevelled segment 46enmeshes with the 'gear 49, turning it with the shaft 50 and gear 53,whereby the shaft 55 will be rotated in a through the motor board as at78 ed member 60 being provided at thev end ofl .the collar 59'forsecuring the flange 58 in rotatable relation to the collar 59, suitablebearings 61 being provided. A portion of the under side adjacent theedge of the flange 58 is provided with teeth forming a rack 62 which isadapted to enmesh with a gear 63 carried upon and rotatable by theshaftv 55; thus, rotational movement of the ange 58 is provided for. themovement being on look-` ing downward upon the fiange counter-clockwiseupon initial movement in response to the bevelled segment 45, androtation of the shaft 55 is indicated bv the arrow A as will behereinafter described upon the completion of this counter-clockwiserotation as indi'- cated bv the arrow A on the flange 58. The flange 58remains stationary until' the rotation of the vgear has advanced so faras to bring the segment 46 into engagement with the gear 49, whereuponclockwise movement of the flange 58 will follow by rotation of a shaft55 in the direction of the arrow (Fig.

For actuating the tone arm in response to movement of theflange 58, anarcuate aperture 65 is provided therein. One end of the aperture 65 isprovided with an lnwardly projecting extension 66.. The aperture 65 isadapted to receive therethrough an operating leverarm 67 secured to thetone arm 15 in any desired manner as shown at 68. The

` lever arm 67 is preferably turned inwardly to conform to the' shape ofthe tone arm 1.5, and thus providing forthe movement of the recordgripping means which will be hereinafter described. Fixedly mounted uponthe collar 59 there is provided a stationary plate 69 provided with anextending camming edge 70 which is adapted to part1allj',7 overlie thearcuate aperture 65. An extending arm 71 is also provided upon rtheplate 69 to which there is pivoted upper and lowel:

tion of the device to various sizes of sound records. y i

By referring to Figs. `12 and 14'it will be noted that the upper camfaced lever 72' is movable about its pivot point by the rotation of themainv drive shaft to which the main driving'gear 43 is xed for'.rotation therewith. A rotating cam 8l is provided upon the shaft 80adjacent thegear 43, and a bell crank 82 is provided pivoted to one offthe main shaft support bearings 83 which are vadapted to extenddownwardly through the motor board 10 to which they are secured asRefcrringto Figs. 12 and 14, itA will be seen that rotation of the shaft8O in counter-clockwise direction will effect movement of the bell crank82 about its pivot, whereby its upper ,face 85 contacts with a link 86pivoted tothe underside of the motor board 10 as lat 87; thus, effectinglinear motion of aconrnesting li-nk'l88'to which the free end of thelink 86 is secured, and in turn causing pivoted movement ofthe upper camfaced lever 72. It has been found preferable to provide a contractingsprin 89between the motor boar-d l0 and shaft 8 ,whereby the shaft willbe normally held in spring urged abutting In theoperation of the tonearm lifting and lriovingmechanism, it may be seen that as the motor 3,4is energized by the operation relation to thesurface 85 ofthe bell crank82. 1

of the switch 20 previously described, the

main drive `gear 43 is rotated in a counterclockwise direction from itsvertical position shown .injFigs 10 and 12, thus bringing in contactwiththe cooperating bevelled gear l48 the bevelled-gear segment 45, wherebytheshaft 5 5' is rotated in the direction of the arrow A, and'causing acounter-clockwise rotation ofthe flange 58 as indicated by arrow Athereon'.A Simultaneous with the beginning of the counter-clockwisemotion of the` y flange 58, the lcam 81 is rotated in a clockwisedirection; thus, moving 'the bell crankA 82 in a counter-clockwisedirection about its.

pivot, and-causingits face 85 to camoutwardcam faced levers 72 and 73respectively. The lower lever 73 is adapted for setting by actuation ofa pivoted link 74 pivoted upon a-n axis 75 depending from the motorboardlld The link 74 is operated by a draw bari'i' V extending under themotor board 10a trated in the dotted lines inFig. 1,. 'y operable by acamming-l level` 77 to the under side thereof atf't)vv a Fig. 5. As willbe hereinafte the actuation of thetcammin r Y adapted to control theamplitude o motibn of the tone arm 15v for conformmg thesopera-.Weeral-.t

curred by one-sixth of a revolution of the ,main driving gear 43.-

Upon completion of the counter-clockwise rotation' of the flange 58 bycompletion of the rotation of the gear 48 by the segmentbevel 45, itwill be seen that the gear 43 is free to travel for two-thirds of arevolution before reverse rotation of the flange 58 is initiated bycooperation of the bevelled gear 46 and gear 49, and the rotation'of theshaft 55 in the direction of the arrow B. It will be seen that duringthis interim of two-thirds of a revolution, the tone arm remains in itsremoved position from above the turntable. By referring to theconfiguration of the cam 81, it will be noted that during this twothirdsrevolution of the gear wheel 43, and thus of the shaft 80 to which it issecured, it will be noted that thecaniming face 85 of the bell 'crank 82is maintained in extended position holding lever 87 againstJ the tensionof the spring 89 in a position whereby the lever 72 will maintain thetone arm in the upwardly'swung position about its axis 17 thus securingthe sound box in the raised position as shown in Fig. 7. Y

. Upon completion of the two-thirds' free revolution of the wheel 43,during which time' the record hasbeen lifted and', turned over as willbe'hereinafter described, the clockwise motion of the flange 58 isinitiated. It

may be readily seen that at this point the mechanism has taken on theposition shown in Fig. 13, thus, clockwise direction of the flange 58causes the extension 66 to engage the arm .67 and thus move the tone armback over the turntable. The bell crank 82 hasthus reached the positionupon the cam 81 where it is free to assume/its mounted position and thespring 89 thus draws the lever 87, whereby the arm 72 will move aboutits pivot and assume a position adjacent the collar59. The

downward movement of the tone arm and sound box is however arrested bythe cam ming surface of the fixed plate 69, and thus continuing theengagement of the arm 67 by the projection 66 until such`time as the arm67 has reached by a clockwise travel the end of the camming face. Whenthis is accomplished the arm 67 moves inwardly towards the vertical axisof the flange 58, thereby lowering the sound box upon the outerperiphery of the sound record. Continued rotation in aclockwise-direction of the flange 58 will not effect movement of thetone arm as the length of the aperture 65 is such as to provide a lostmotion connection.

By referring to the switch mechanism, it willbe seen that uponlowering'v the tone arm, the switch is operated to cut off power fromthe motor 34 and initiate the motor 14, thus the tone arm is moved andis free to move across the record, reproducing soundpwaves in the usualmanner; the motor 34 having been stopped atA the neutral -position ofthe gear wheel 43.l

By referring to Figs. 15 and 17, it will be seen that movement of thedraw bar 76 causing rotation of the pivoted link 74 about its pivot 75,causing the lower cam faced lever 7 3 to 'move outwardly from the collar59, will bring its cam surface in a position to overlie the cam face 70of the fixed cam 69, whereby inward swinging movement of the tone armwill be caused to continue beyond that previously described inconnection with the movement ofthe arms 67 over the cam face 70. Thus,when it is desired to operate the device for small diameter records, thedraw bar 76 is moved to the position shown in Fig. 15; the differencebetwee'n the lowering points of the tone arm being indicated by thedotted lines.

For operating the record reversino mechanism, the shaft 80 extendstransversly under the motor board 10; the end opposite the driving gear43 being journalled in a pair of spaced supporting members which arecarried vfrom a plate 91 which is adapted to fi't over an aperture inthe motor board 10. Mounted between the members 90, a shaft 80 carries apair of cams 92 and 93 rotatable therewith, midway between which a camwheel'94 'is provided and a mutilated gear 95 is mounted between the camwheel 94 and the cam 93; all of these members being secured to theshaft-80 for rotation therewith.

The supporting members 90 are adapted to extend above the surface of themotor board 10. Between their upwardly extending extremities there isprovided a shaft 98-- threaded cap 104 which is apertured to pro.

vide a bearing forthe push rod 102. The opposite end'of the liner mayalso be closed with a cap 105, also apertured to form a bearing for thepush rod 102. It will be notedl that the expansion spring 103 abuts theinner face of the cap 105- at oneend, while the opposite end is adaptedto bear against a cross pin 106 extending through the push rod. The

collar end of the push rod. 102 is preferably provided with a bifurcatedextension 107 between the bifurcations of which a suitable collar 108may be provided. The opposite end of the -push rod 102 is secured to apair of arm operating links 110, the operation of .which will behereinafter described. Surrounding that portion of the liner 101 whichextends out from the collar 1 00, a rotating sleeve 111 is provided,upon the inner end of which a bevelled gear 112 is secured for rotationwith the sleeve 111. Extendin from diametrically opposite points on thesldes of the sleeve 111 ears 114 are provided to which arm pieces may bepivoted as will be understood from the further description of theapparatus.

D Y Mounted on either side of the collar 100 upon the shaft 982 a fullyrotatablemutilated bevelled gear 115 1s provided, and on the other sideof the collar 100 a complete bevelled gear 116 also fully rotatable withthe shaft 98 is also provided. Mounted between the supporting member 90and the gears 115 and 116 a pair of ratchet wheelslla and 116arespectively are provided, and are part of the gears 115 and 116respectively. Levers 117 1 are provided mounted securely on the shaft98, their upper ends being provided with oppositely disposed pivotedpawls 118 which are adapted for cooperation with the oppositeinclination of the ratchets llaand 116e.

5 For causing longitudinal motion of the push rod 102 the cam wheel 94is provided which is adapted'to move about its pivot a gripping leverv120 which bears upon the wheel 108, thus upon inward movement, causinglinear motion of the push rod 102 against the tension of the spring'103.For gripping the record and lifting it from'the turntable, there isprovided a pair of hinged arms 121 hinged as at 122 by the provision ofa bifurcated end and extending tongue, the interrelation of which isclearly illustrated in Figf 4. The short hinged extension 123 of thearms 121 is pivoted in the ears 114 of the,

sleeve 111 as seen 'm Fig. 1. Movement about the pivot oint of the ears114 being controlled by t e arm-operating links 110 associated withtheextremity of the push rod 102.

At the hinged connectionV of the arms 121 with the extensions 123,contracting springs 124 are provided which ma be preferably j oined toVtherespective mem ers by protrud-V ing pins 125.

The extremities of the arm 121 are provided with record ,gripping meansillustrated in detail in'Figs. 8 and 9; the extremities of the armsbeing apertured as at 126 to receive therethrough a pairof supportingmembers 127 urged outwardly from the arms 121 by springs 128. Theinnensupporting member 127'is preferably rigidlyv secured to thegripping'base 129 while the outer member 127 is pivoted thereto, thebase 129 may preferably be substantially U-shaped in cross section, itsfree end gripping therebetween a resilient pad 130 which may bebifurcated toA form a recess 131 within which the. record adapted tofit. The pad 130 may preferably be formed -of rubber, felt or-othersuitable 127, together with the enlargementof the aperture 126 for theinner support 127, that controlled and dampened play of the pad 130 pingfor various record edges. t willbe further .noted that by the hin edstructure of p may take place, thereby insurm proper gripi the arms 121,that they may e bent outward 1y to accommodate the reception of varioussizes of phonograph records. l

The operation of the record elevating and turning mechanism may bedescribed as' fol- Y lows. Y When the end of the bevelled segment hasreached the gear 48, as vreviously discussed, the tone arm and soun boxhave been moved to the position indicated by a dotted line in Fig. 15,whereby they are in a position leaving the record free to be lifted andturned. It will be remembered that by the configuration of the segmentalgears 45 and 46 that a two-thirds revolution of the gear 43 wardly fromthe shaft thus, moving to'Y ward the turntable, the push rod 102 againstthe tension of the spring 103 by connection of the upper cam surface ofthel lever 120 with the wheel 108 and held in this-position until theend of a full revolution of the shaft 80 when lever 120 will slide intothe notch of the cam wheel 94. By referring to Fig. 1

it will be noted that this rectilinear motion inwardly of the push'rod102 moves inwardly the arm-operating links110, and it may be readilyseen that such movement will cause a contraction ofthe arms 121 movingthe record-gripping means toward eachother by pivotal movement of thearms 121 with re-A spect to the ears 114. In this connection it will benoted that if the record is of large diameter as shown by the full linesin Fig. 1,

the record will be received Within the recessv 131 .and further inwardmovement caused by the links 110 will effect a hinged movement at thepoint 122 against the tension of the springs 124i On the other hand,shouldifthe record be small as shown by the dotted lines ,in Fig. 1, thecontinued movementcff-the arms 121 inwardly will grip the edge of-.the

record without causing hinged motion of' the arms 121'; thus, .the armsvautomaticallycompensate for varym sizes of records, and in each instanceregar less of size,the arms move inwardly, receiving the record withinthe recess of the pad 130, and by the spring;

' associated withl the supporting members 12 the record will bejgrippedand-firmly. held by tion of one full rotation of the gear 43 until thelever4 120 slips into the notch of cam 94. Note that theconiguration ofthe similal` Vthe arms v'121,and so eld until the -expirafH cams 92 and93 is such that they will rotate freely about one-fifth of the rotationof the drive ear 43. By further advancing said cams, t ey will strikelevers 117 causing upward movement towards the turntable, being securelyfastened 0n shaft 98; 98 being part of the T-shaped bushing 100. It willbe seen that further movement of cams 92 and 93 will cause raising ofthe arms .121 to lift the record.

The gear 116 is free to rotate about the shaft, its action being merelyto retain in proper alignment the bevel gear 112. It. will e also notedthat the pawl engageable with the ratchet 116a is free to slip over theratchets. When vthe cams 92 and 93 have moved the arms 117 to thefurthest extended position, they will retain the cams in this positionfor approximately one-third of the rotation of the gear 43, as will beseen by refer- (nce to the coniguration of the camming surace.

During the period ofelevated raised position of the lifting arms, whenthe levers 1-17 are held outwardly by the curved surface of the cam 92and 93, it will be readily seen that the mutilated gear 95 is moved toengage the peripheral gear teeth of the mutilated gear thus, rotatingthe mutilated gear 115 about the shaft 98, whereby its mutilatedbevelled gear teeth will engage the gear 112 and rotate it with thesleeve 111 about the liner 101; thus, by the push rod swivelconnection'of the ears 114, it will be seen that the record is rotatedabout a diametrically extending axis in line with the pushrod 102.

It will be readilyunderstood that the gearing ratios and mechanicalmovement coordination is such that the record will be rotated one-halfof a revolution. Continued motion of the drive shaft 80 thus causes thegear teeth of the gear 112 to pass from the teeth of the mutilated gear115, whereby rotation is ceased, and shortly thereafter the cammingsurfaces are moved to permit the arms 117 to assume their normalposition,

ythus lowering the record carrying arms to vreplace the record upon theturntable with its reverse side uppermost.

The above movements of lifting, turning and replacing having beenaccomplished in the two-thirds rotation of the gear 43, it will beunderstood, referring to the operation of the tone arm, that at thetermination of this free two-thirds rotation of the gearv 43, the tonearm is moved inwardly and lowered upon the peripheral edge of thesurface of the record.

The coordination of the various movements willl be readily. understood.Commencing with the sound box at the expiration of the sound groove ofthe record Vas previously described, the energy to the motor 14 is cutoff while the motor 34 is energized. Thus, the .shaft 8O throughactuation by the gear 43 is caused to rotate from the neutral positionof the segmental gears. The tone arm is then raised andremoved to apoint away from the upper surface of a soundrecord, and is maintained inthat position while the record arms move inwardly to grip the rec- 0rdand then raise the record and reverse it; and moving downwardly todeposit the reversed record upon the turntable. The push rod is thenallowed to move inwardlyto release the record, and upon completion ofthis movement which has so far consumed fivesixths of the revolution ofthe shaft 80, the opposite segmental gear comes into play, returning thetone arm to a position above the record and positioning the sound box onthe outer peripheral edge of the record, whereupon the switch mechanismacts to cut off power to the motor 34 and initiate movement of the motor14 as substantially herein described.

Thus, it may be seen that my invention provides a completedautomaticmechanism, whereby opposite sides of a record may beplayed-'without any 'manual manipulation of the apparatus. The operatlonof the device is continuous and opposite sides of the record may besuccessively played for any desired period of time without requiringanyA attention from the operator of the-mechanism.
